Unambiguous substance identification is a pre-requisite to most of the REACH processes. Actors in the supply chain must have sufficient information on the identity of their substance.

The correct identification of a substance will enable, for example:

• The sharing of information by potential registrants and data holders to prevent the duplication of testing on animals and unnecessary costs
• The assessment of the applicability of test data across companies who registered the same substance, the assessment of read-across proposals (categorisation approach) or the use of non test information
• The assessment if a substance is included in the Authorisation List, the list of restrictions or if its classification and labelling has been harmonised

The following information on the manufactured or imported substance shall be included in the dossier in order to unambiguously identify the substance:

• Substance name and related identifiers, molecular and structural formulae, if applicable
• Information on the composition and purity of the substance
• Spectral data and analytical information to verify the identity and composition of the substance
• Clear and concise description of the analytical methods
